"DUMPING-SCOW.

SPECIFICATION forming part of Letters Patent No. 289,498, dated December 4, 1883.

Application filed July 2?], 1883. (No model.)

To all whom it may concern.-

Be it known that I, MoRRIs F. BRAINARD, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Dumping-Scows, of which the following is a specification.

My invention relates to that class of dumping-scows for transporting refuse or material of any kind from place to place wherein the load is carried upon the deck of a float.

My object is to devise a scow that will discharge its load in a more effective and rapid manner than can be done at present,'and to meet the requirements of the various materials to be handled, being more substantially constructed, and also better adapted to withstand a rough sea than those now used. I attain this by erecting upon the deck of a float bins or receptacles for holding the material, which are hinged or pivoted to the sides of a float, and extending to the center of float. The bins being securely pivoted to the sides of float, the other or inner side of the bin is raised to a sufficient incline to allow the load to slide off freely, which will be hereinafter more fully explained, reference being had to the accompanying drawings, in which- Figure 1 represents plan view of scow, part of deck and the bins removed. Fig. 2.is a side elevation, part in section at a: a Fig. 1.

Fig. 3 is an endelevation section at y 3 Figs.

1 and 2, one of the bins raised for discharging load. Figs. 4. and 5 show other methods of applying the screw for raising the bins. Fig. 6 represents (enlarged) view in section of swinging nut and yoke.

Similar letters refer-to similar parts in the several views.

A represents float, to which the bins or receptacles B are pivoted or hinged at a a a to the bottom timbers of the bin B, and near the opposite side. From the hinges lifting-screws O are pivoted at d, and, extending downward through the deck, engaging with the nut 12. The nut 72 is fitted into a swinging yoke, D, suspended from the deck in a suitable frame, 6. The yoke D swinging freely therein, the screw is thereby always in a direct axial line with the pivot 01 when the bin is being raised .for raising each bin B. I have shown three,

which I consider are sufficient, and these are all worked simultaneously by the connectingshafts f and gears f, which also revolve all the nuts b, connected, as shown, in one set. Motion is imparted to the shaft f from the machine E by cross counter-shaft h, gear h, and clutch g.

When a bin B is to be discharged, the side hinged at F is unfastened and dropped outward, as shown, the machine E having been previously started. The respective clutch g of said bin is thrown in or engaged with machine E, whereby motion is imparted to the nuts 12 by gears h f, and shafts h f, revolving the nut b and raising the lifting-screws O, which tip or tilt the bin 13 upon the pivot a and cause the load to slide out. When the load is discharged, the motion of the machine is reversed and the bin is again lowered upon the deck and firmly held there by the said liftingscrews until reloaded, and cannot be moved by the rough sea it may encounter.

The device as shown in Figs. 4 and 5 is applied when long lifting-screws are not desired. I firmly secure to the bottom timbers of bin B a toothed segment of a circle, H,into the teeth a of same. A short worm, 0, is engaged for raising or lowering the bin. (Shown in Fig. 4.) In Fig. 5 a spur-pinion, n, is engaged with the segment H, which in turn is operated by screw or worm gear 8 s, the movements of which, are familiar to all. In both of these devices they are connected by suitable gearing with the same machine E as is above mentioned, and operate in same manner as the screws 0. Thus it will be seen that I have a strong and substantial scow, able to withstand a rough sea without injury, easy to manipulate, and rapid in its operation of discharging a load of all kinds of material, garbage, sand, mud, &c., and especially adapted for handling stone and other rough material, and by using independent bins on each side I am enabled to unload stone back of dikes or cribs, which is very essential where place of deposit is exposed and quick dispatch required, also making a large saving in expense of unloading by labor, as required by scows, and by removing the bins B, I have a float with all the required equipments for raising wrecks or other obstructions of the harbor and channel.

What I claim, and desire to secure by Letters Patent, is

1. In a dumping-scow with bins upon the deck thereof, the bins B, firmly attached by hinges on the outer side to the outer side of the deck of the float A at a a, and held securely thereto while the inner or other side is raised and lowered for discharging the load by suitable mechanism,substantially as described.

2. In a dumping-scow, the floatA, with lifting-screws O, and the driving mechanism for said screws therein for raising or tilting the bins B to discharge same, substantially as described.

3. In a dumping-scow with bins B, having pivoted thereto the lifting-screws 0, nuts b and swinging yoke'D, for the purpose specifled.

4. In a dumping-scow, the combination of 5 the float A, bins B, lifting-screws 0, nuts I), yokes D, and driving mechanism E, operating in the manner described, substantially as and for the purpose specified.

Signed at New York, in the county of New York and State of New York, this 19th day of July, A. D. 1883.
